Fixation Loss how many times the patient looks away from the central target. From this baseline, GPA is able to provide both event- and trend-based progression analysis on future tests (. Electroretinography (ERG) is an eye test in which electrodes are placed on the cornea to measure electrical responses to light in an effort to detect abnormal retinal function. If a patient with visual field loss is being monitored with serial examination, use the mean deviation (MD), pattern standard deviation (PSD) and visual field index (VFI) to track progression. Common threshold patterns are 10-2, 24-2, 30-2 and 60-4. Kaushik S, Mulkutkar S, Pandav S, et al.

The target may be a small disc on a stick, but most commonly the target is the doctor's hand holding up one or two fingers. These defects originate from damage to the arcuate nerve fiber bundlesoften visible on funduscopy with retinal nerve fiber layer (RNFL) wedge defects or neuroretinal rim notching. 2006;15(2):152-7. Trigger happy patients will push the response button in the absence of a stimulus. Herbolzheimer W. Computer program controlled perimetry, its advantages and disadvantages.

The best tools for progression analysis on HFA units are GPA Change Probability, VFI trend, and MD trend, and linear regression and cluster regression analysis on Octopus units. Your visual field is how wide of an area your eye can see when you focus on a central point. In addition, the skin is weighed down by the effect of gravity. Heijl A, Bengtsson B, Chauhan B, et al.

Modern perimeters are equipped with powerful software tools that allow practitioners to accurately track these metrics. 1. Field analysis in glaucoma relies primarily on the 24-2 and 30-2 patterns, as the majority of ganglion cells lie within the central 30 degrees of fixation.3 Use of 24-2 has become increasingly prevalent as the test of choice in glaucoma due to its faster testing time and reduced trial lens and lid artifact errors. Scott, for example, had additional heaviness on her outer corners, so her doctor tailored the incision almost like a winged eyeliner to help pick up those outer corners. Extensive RNFL loss (~30%) is necessary to produce a visual field defect.22,23 An individual (especially a patient with a large optic nerve) may have as much as one third of her or his RNFL deteriorate while still maintaining green normative levels on OCT analysis (this is often referred to as green disease).24 A recent study reported the highest correlation between progression on OCT and visual field to occur at a 10m RNFL loss on SD-OCT.25 For many patients, advanced glaucomatous optic atrophy will result in a severely depressed RNFL that does not allow for proper detection of progression.
